The invention discloses a signal feedback device integrated on a butterfly valve or a ball valve. According to the signal feedback device integrated on the butterfly valve or the ball valve, a signalcollection box connecting shaft is fixedly connected with a turbine box of the butterfly valve or the ball valve through a key; a signal collection box cam fixedly sleeves the signal collection box connecting shaft in a signal feedback box shell; a microswitch is fixedly arranged in the signal feedback box shell; the microswitch is electrically connected with an aviation plug arranged outside thesignal feedback box shell; and when the signal collection box connecting shaft rotates, the signal collection box connecting cam rotates along with and contacts with the microswitch, the microswitch is triggered to send a feedback signal, and the feedback signal is transmitted to a control console through the aviation plug. The signal feedback device is arranged on a worm gear box for driving thebutterfly valve or the ball valve to open and close, is integrated with valve bodies, and does not need to be observed on site, so that operators observes the opening and closing state of the valves through feedback signals in a control room, and the operation is convenient and efficient. Because the feedback device is integrated with the valves, the signal feedback device is arranged inside the valves, and the tightness of the valves is guaranteed.
Description
technical field [0001] The invention relates to the technical field of butterfly valves / ball valves, in particular to a signal feedback device integrated in butterfly valves / ball valves. Background technique [0002] In many pipeline systems, valves control the flow of media, and the working status and sealing of valves affect the operation of the entire pipeline system. Due to the large space in the cabin, the distance between the control room and the location of the valve is very far. If there is a problem with many old-fashioned valves, it needs to be observed on site to eliminate the problem, which greatly affects the work efficiency and is very inconvenient. In order to solve this problem, a signal feedback device can be installed on the valve to transmit the signal directly to the control room, which can accurately locate the problem. At present, there is a signal feedback device that can be directly installed on the valve for use on the market, but this signal feedba...
